Gas fitting is one of the most strictly regulated trades in Australia — and for good reason. Gas leaks can cause fires, explosions and carbon monoxide poisoning. The NSW regulatory framework for gas work is designed to ensure all gas installations, repairs and modifications are carried out by licensed professionals to specified standards. Understanding what the rules are, what you're legally permitted to do yourself, and what requires a licensed gas fitter helps Newcastle homeowners make safe, compliant decisions.
Who Can Do Gas Work in NSW?
Under the Gas and Electricity (Consumer Safety) Act 2017 (NSW), only a person holding a current gas work authorisation (gas fitting licence) issued by NSW Fair Trading can carry out gas fitting work. This includes:
- Any connection of gas appliances to a gas supply line
- Installation of gas supply lines and fittings
- Disconnection and reconnection of appliances
- Testing and commissioning of gas systems
- Repair of gas lines, regulators and fittings
Unlicensed gas work is a criminal offence in NSW, punishable by significant fines. It also voids your home insurance for any damage resulting from the unlicensed work.
What You Can Legally Do Yourself
The only gas work a non-licensed person can legally perform is connecting a portable gas appliance (such as a portable LPG barbecue) to a refillable LPG cylinder using a standard, approved regulator and hose assembly — provided no permanent gas fitting work is involved. That's the complete list.
You cannot legally: connect a fixed gas cooktop, oven, or heater to a gas point; install a new gas point; replace a gas regulator on a fixed installation; or carry out any repair to a fixed gas line or fitting. All of these require a licensed gas fitter.
What a Licensed Gas Fitter Does in Newcastle
Appliance Installation and Connection
Gas cooktops, ovens, freestanding ranges, gas heaters, gas fireplaces, gas dryers, gas hot water systems and BBQ gas points — all require connection by a licensed gas fitter. Installation includes: checking gas supply pressure is within the appliance's operating range, connecting the appliance to the gas supply, pressure testing the connection, and issuing a compliance certificate where required.
Gas Line Work
Running new gas supply lines to new locations — extending existing gas infrastructure to a new BBQ point, adding a gas line to a renovated kitchen, or providing gas to a new room — is regulated gas fitting work requiring design, installation and pressure testing by a licensed fitter, followed by a compliance certification.
Gas Leak Detection and Repair
Locating and repairing gas leaks using electronic detection equipment, visual inspection and pressure testing. All gas leak repairs must be certified compliant by the attending licensed gas fitter.
Gas Compliance Certificates
A Certificate of Compliance (CoC) is required for certain gas work in NSW — new gas installations, extensions to existing gas systems, and in some cases repairs. This certificate confirms the work meets Australian Standard AS/NZS 5601 and is required for property sales and insurance purposes. Only a licensed gas fitter can issue a CoC.
Gas Emergency: What to Do
If you smell gas:
- Don't use electrical switches — don't turn lights on or off, don't use any electrical appliance
- Don't use your phone inside — the electrical activity can ignite gas
- Extinguish any naked flames immediately
- Open windows and doors to ventilate if you can do so without switching anything electrical
- Turn off the gas at the meter (outside, usually near the front of the property) if safe to do so
- Evacuate the building and call from outside: us on 0491 570 006 for emergency gas fitter attendance, and if you believe there is immediate danger, also call your gas supplier's emergency line
